Specification of Letters Patent.

Patented Mar. 8, 1921.

Application led August 6, 1920. Serial No. 401,613.

To all 'whom t may concern.'

Be it known that I, JOSEPH STYRBINSKI, a citizen of the United States ofAmerica, re-

siding at Michigan City, in the county of,

for its primary object to provide an ash sifter embodying an inclosingcasing with a vibratory sifting screen suspended therein.

A further object of the invention aims to provide in-an ash sifter, acasing having a vibratory frame with a sifter screen supported thereonand operable eXteriorly of the casing, a removable tray being slidablyassociated with the bottom of the sifter casing for removing thescreened ashes therefrom.

With these general objects in view and others that will appear as thenature of the invention is better understood, the same consists in thenovel construction, combination and arrangement of parts hereinaftermore fully described, illustrated in the accompanying drawings, andpointed out in the appended claim.

In the drawings forming a part of this application and in which likedesignating characters refer to corresponding parts throughout theseveral views,

Figure 1 is a side elevational View of an ash sifter casing constructedin accordance with the present invention,

Fig. 2 is a top pla-n view of the same with the cover removed, andpartially broken away to show the sifter screen mounted upon thevibratory frame within the casing and the operating arm for the frame,

Fig. 3 is a vertical cross sectional view taken on line III-III of Fig.1, showing` the ash receptacle at the lower end of they casing.

Fig. 4 is a fragmentary sectional view showing the vibratoryscreen-supporting frame, and

Fig. 5 is a detail fragmentary perspective view of a portion of thescreen-supporting vibratory frame.

Referring more in detail to the accompanying drawings there isillustrated an ash sifter embodying a casing having side walls 1 and 2and end walls 3 and4 carried by the bottom wall 5 supported on cornerlegs 6, the upper end of the casing being provided with a cover 7,hinged as at 8 to the side wall 2 and carrying an ordinary hasp 9 at thefree end thereof for engagement with the side wall 1 of the casing, thecover being more clearly shown in Figs. 1 and 3.

As shown in Figs. 1 and 2, lifting handles 10 are carried by the endwalls 3 and 4. A vibratory screen-supporting frame is suspended withinthe casing and includes side strips 11 secured by the rivets 12 to theupper edges of the side walls 1 and 2 as shown in Figs. 3 and 4 andpositioned beneath the inwardly-bent upper edges 13 of the side walls.The strip 11 adjacent each end thereof is bent upon itself 'to provide aU-shaped bracket 14 in which is secured the upper end of a resilienthanger strip 15, a mounting strip 11 being positioned on each side wallof the casing with the lower ends of the resilient hanger strips 15connected to the angle ends 16 of the transverse bars 17, thus forming arigid connection between oppositely-positioned hanger strips. As shownin Fig. 4, a longitudinal supporting strip 18 connects the transversebars 17, the strips being secured thereto as at 19. A rectangular frame20 has the lower edge thereof inwardly-flanged and is attached as at 21to the supporting strips 18 to provide a supporting frame for the sifterscreen. A sifter screen 22 is of rectangular formation as shown in Figs.2 and 3 and has a reticulated bottom wall 23 with the entire screenmemhandle 31 is positioned in the lower end of.

the casing and is adapted to be removed therefrom to dispose the ashesand other refuse sifted from the screen and received therein.

Assuming that the sifter screen 22 is filled with material to be sifted,such as ashes, with the cover 7 closed in the position shown in Figs. land 3, theV handle 27 shifts the arm 24 upon the pivot 25 to reciprocatethe vibratory frame suspended by the resilient strips l5, the strips 15vibrating and carrying therethrough the frame 20 which supports thesifter screen 22 and a single movement of the handle 27 will communicatea series of continuous vibratory movements to the sifter screen withinthe casing, it is believed that the constructionand operation will atonce become apparent, it being noted that the resiliency of the strips15 provides for continuous successive vibratory movements in response tothe operation of the handle 27.

While the form of the invention herein shown and described, is what isbelieved to be the preferred embodiment thereof, it is nevertheless tobe understood that variousforms, modifications and arrangements of theparts may be made without departing from the spirit and scope of theinvention as claimed.

Having thus described my invention, nwhat l claim as new and desire tosecure by Letters Patent, is

An ash sifter of the type described comprising a casing, a side stripsecured to each side of the casing adjacent the upper edges thereof,each strip being bent outwardly adjacent the ends thereof to providebrackets, flat resilient strips having the upper ends thereof secured inthe strip brackets with the major transverse axes thereof extendingtransversely of the casing, a transverse bar rigidly connecting thelower ends of the resilient strips and spaced from the sides and ends ofthe casing, longitudinal strips secured to the transverse bars andprojecting outwardlypof, the same, a rectangular frame secured to theends of the longitudinal strips, a sifter screen supported on thelongitudinal strips within the rectangular frame, an arm projectingoutwardly from one of the transverse bars, and a handle lever pivoted ina side wall of the casing and with the inner end thereof connected tothe free end of the arm for vibrating the sifter screen supportingframe.

In testimony whereof I affix my signature.

JOSEPH STYRBINSKI.
